RELATED: Woman accused of killing man while he filmed her found guilty of murder
Prosecutors said Harp shot Rahim Grant seven times in a Clayton County apartment on Dec. 29. He died of his injuries.
Grant’s mother, Geraldine Grant Bryson, previously said Harp was obsessed with her son. Soon after Harp was arrested, Grant Bryson told Channel 2 about her son’s troubled and tumultuous relationship with the woman.
She said she told him to get out his phone and start recording whenever he felt he was in trouble.
"(I told him) get the video, record it and lay the phone down," she said.
Grant did that and recorded his own murder, Channel 2 previously reported.
Initially, police were not able to get evidence from Grant's phone. Authorities eventually got their hands on it and saw footage of Harp shooting Grant as he begged for water and expressed a desire to hug his daughter, Channel 2 reported.
“It broke my heart,” she said. “ ... It's something you don't think when you just talked to your son.”
On the witness stand in court, Thurmond said her daughter was manipulative, connived her way through life and “reveled in disrespect and foolishness.”
“Wherever you went,” she said, “chaos and trouble were sure to follow.”
Thurmond said Harp was upset at Grant for ending their relationship, according to Channel 2.
“Your envious nature took control, and you murdered Rahim for moving on without you,” she said.
Harp countered by sneering and mouthing profanity at her mother, Channel 2 reported.
“You repeatedly hurt the family,” Thurmond said. “Our family.”
